Description

Solenoid arrangement for door handle control

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a handle control solenoid arrangement in a door lock, in which the transmission of force from the operating axis of the handle or the like to the driver acting on the latch is arranged by a movable coupling member driven by the solenoid arrangement.

BACKGROUND OF THE INVENTION

Control of the handle or handle of the door lock by means of a solenoid arrangement may be provided in various ways depending on the application.

For example, the arrangement may be such that when the solenoid is energized, it permits passage using the handle, thereby engaging a power transmission from the handle at the latch of the door lock.

Alternatively, the solution may be reversed such that the arrangement allows for passage using the handle when the solenoid is not powered.

The mode of operation of the arrangement depends on whether the safety of providing passage to or exit from the locked space or the safety of the locked space as such is emphasized.

In practice, the arrangement is generally such that from the outside, the door can always be opened by means of a key controlling the lock mechanism or the like, while from the inside it can be opened by means of a handle, handle, knob or the like. using a two-piece or split shaft for appropriate control.

A practical problem with the above arrangement is that it is necessary to use two separate versions of the lock case for the door lock, one for each type of operation.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide a novel solution of the type in which the same basic components installed in the door lock housing can be used for both of the above-mentioned actuation methods. of the castle.

It is a further object of the present invention to provide an arrangement that is convenient and operationally safe, while not requiring too much space in the lock housing.

The above objects have been accomplished in accordance with the present invention by providing a handle control solenoid arrangement for a door lock in which the transmission of force from the progression axis of the handle or the like to the drive member acting on the latch is arranged by a movable a coupling member that is driven by the solenoid arrangement. The solenoid arrangement comprises a shaft member which is arranged to move through the solenoid against the force of the spring and which moves the rotary lever member to select the operating position of said coupling member. In addition, the position of the pivot axis of said lever member relative to the coupling member is optionally variable to provide the desired handle control.

Thus, the present solution is essentially based on the fact that the axis of rotation of the lever member 5 can be located at different locations, and the location of the lever can be changed very easily if necessary.

In a practical preferred embodiment, the lever member is mounted on the shaft member such that the position of the axis of rotation of the lever member can be changed from one side of the shaft member to the other, with some movement of the shaft member causing rotation of the head of the lever member in a different direction with respect to the coupling.

A compact arrangement can be achieved if the axis of rotation of the lever member is parallel to said operating axis.

In such a case, the arrangement may advantageously comprise a selection member disposed outside the door lock housing and comprising a pivot shaft which may be inserted within the door lock housing so as to cooperate with the lever member and in each case serve as its axis of rotation.

An advantageous solution in terms of space and safety can be achieved if the lever member comprises two sleeve members for said pin shaft, one of the sleeve members being located at the end of the lever member opposite the coupling member.

The change in position of the axis of rotation of the lever member may preferably be provided by changing the position or adjustment of the selection member.

After selecting the desired actuation procedure, the selection member may preferably be attachable to the door lock housing by means of a screw or the like.

In a preferred embodiment of the present invention, the end of the lever member near the coupling member is provided with a magnet for attracting the coupling member.

DETAILED DESCRIPTION OF THE INVENTION

In the drawings, the reference numeral 1 designates a door lock housing 1 having a cover 50 which is shown partially open in the drawings. The door lock housing 1 is

The door lock housing 1 is further provided with an operating axis 3, to which a driving member 4 is arranged, which is rotatably connected to the door lock housing 1, and which, in the case shown in FIG. The embodiment acts on the lock bolt 12 by means of a separate force transmission lever 5. If desired, it is also possible to arrange the drive member 4 to move the lock bolt 12 directly.

In practice, the drive member 4 can be influenced from both sides of the lock. A key-operated lock mechanism or the like, provided with a torsion arm or a respective power transmission element (not shown) acting directly on the driver 4 is installed on the operating axis 3 on the side of the door lock housing 1 in a manner known per se.

Alternatively, depending on the situation, the handle, the handle or the like can also be installed such that the respective spindle acts directly on the driver 4. Here, the door can always be opened from this side.

On the other side of the door lock housing 1, a handle, handle, rotary knob or the like is mounted on the operating axis 3, wherein the spindle (not shown) is independent of said force transmission element, or said alternative handle arrangement may be such that be independently performed accordingly.

The power transmission required to operate the handle is provided by a connecting member 6 having two selectable operating positions, a power transmission coupling in which the door lock bolt 12 can be moved by means of the handle control, and a power transmission disconnection position, which lock bolt 12 cannot be appropriately influenced by the control of the handle or handle.

The handle or handle is operated by an arrangement according to the present invention which comprises a solenoid 10 which moves the shaft member 9 against the force of the spring 8. A lever member 10 is provided on the shaft member 9 which acts on the coupling member 6 so that it is possible to select whether or not the connecting member 6 is in a position interconnecting the force transmission.

The lever member 10 is provided with sleeve members 10a and 10b that are located on opposite sides of the shaft member 9. The arrangement also includes a selection member 11 that can be secured by a screw 13 on the outside of the door lock housing 1 and which is provided with a long pin. shaft 11a and short shaft 1 lb. The select member H may be arranged in cooperation with the lever member 10 such that the long pivot shaft 11a is disposed only on one of the sleeve members 10a and 10b. The door lock housing 1 is provided with holes 1a and 1b for the pin shafts 11a and 11b.

In the situation shown in Figures 1 and 2, the solenoid 7 is not energized, with the spring 8 pressing the shaft member 9 in the direction of the arrow. As a result, the lever member 10 is rotated in its sleeve member 10a about the long pivot shaft 11a of the selector member H counterclockwise as shown in FIG. 1.

In this case, the lever member 10 is provided with a magnet 14 which draws the link member 6 to the non-coupling position, the handle mounted on the operating axis 3 not being coupled to the driving member 4 for transmission of force and thus to the door lock bolt 12. Instead of a magnet 14, a spring force can also be used to move the coupling member 6.

When the solenoid 7 is energized, the shaft member 9 moves against the spring force of the spring 8, with the lever member 10 rotating in a clockwise direction and pressing the coupling member 6 into the coupling position. For the sake of simplicity, no interpretation of the power supply is given here.

-3GB 300450 B6

FIG. 3 and FIG. 4 illustrate how the operation of the handle or crank can be changed by changing the position of the selection member 11.

This is simply done so that the screw 13 is removed and the selection member 11 is rotated by half a turn, so that the position of the pivot shafts 11a and 11b in the holes i and 1b is changed. In this situation, the long pivot shaft 11a is located in the sleeve member 10b.

Consequently, as shown in FIG. 5, when the solenoid 7 is not energized and the spring 8 presses the shaft member 9 in the direction of the arrow, the lever member 10 is rotated in its sleeve member lob clockwise as shown by the arrow while simultaneously presses the coupling member 6 into the coupling position.

Here, the handle or handle, installed on the operating axis 3, is in communication with the drive member 4 so that the lock bolt 12 can be actuated by means of the handle or handle. If, in this situation, the solenoid 7 is energized, the direction of movement of the various members is changed, with the connecting member 6 being moved by its magnet H to its non-coupling position.

The present invention is in no way limited to the embodiment shown, as many variations thereof may be made within the scope of the appended claims.
